As others have said, this is a crowded space...with a lot of opportunity for a clear leader to emerge (IMO). $10/mo isn't a bad deal, but I really think you need to go way above what you're thinking here to dominate this. Offer to keep a backup/cache of the site at a known point (this is basically a 1-line wget script). Offer some haproxy-bsed auto-failover auto-maintenance page stuff for when a site does eventually go down or get fubar'd. From my personal perspective, it's good to know when something goes wrong, but it's fantastic to also be able to have some auto-fail or recovery option available (automatic, or user-initiated from an iPhone app) so that if I can't get online to rectify the situation promptly, I at least know users are being hit with 404's and SQL errors, etc.
